Agriculture in the region of mezcal, sustained in the production of agave and in small production units, does not allow for the domestic reproduction of UDC. The members this UDC amount of economic activities including agriculture and non-agricultural activities for their reproduction, especially international migration, which dominate the formation of the overall revenues. This condition does not necessarily mean the disruption of agricultural activities, but on the contrary is refuncionalizada by the transfer of resources through remittances, in terms of demand for agave tequila-producing companies, expanding production. This shows the integration of economic activities performed by the UDC, and no opposition between them.
